Washington Avenue begins at Eagle Street, opposite the Albany City Hall, in Downtown Albany. Heading northwest, as a four-lane road, Washington Avenue moves past the northern side of the New York State Capitol as it climbs in elevation away from the Hudson River. From its beginnings at Eagle Street, Washington Avenue carries New York State Route 5. Continuing northwestward, Washington Avenue intersects with Lark Street (US Route 9W), and then loses its designation as Route 5 to Central Avenue, which ends at the Washington intersection. After meeting Central Avenue, and intersecting Henry Johnson Boulevard, Washington Avenue runs past the SUNY Albany Downtown Campus, and forms the northern boundary of the Pine Hills neighborhood. Moving further uptown, Washington Avenue crosses over the Crosstown Arterial, New York State Route 85, while providing access to that route southbound from the westbound lanes, and northbound from the eastbound lanes. The W. Averell Harriman State Office Building Campus can be accessed from eastbound lanes and from the westbound lanes via the Patroon Creek Corporate Park. Washington Avenue continues it northwest course by paralleling Interstate 90 as a four-lane divided highway, and forms the northern boundary of the SUNY Albany Uptown Campus. Washington Avenue provides three separate entrances to the campus, as well as access to the eastbound side of Interstate 90 via that highway's Exit 2. Washington Avenue at a two-level roundabout with Fuller Road continues onwards as Washington Avenue Extension (officially known as New York State Reference Route 910D). As Washington Ave Ext, the highway continues as a four-lane divided highway, with an interchange for the Crossgates Mall in neighboring town of Guilderland, and intersections for access to several access roads parallel to the highway. The access roads have Crossgates Commons, a shopping center in the city of Albany, along with numerous business/corporate parks and the Dunes neighborhood. Washington Ave Ext ends at the intersection with New Karner Road (NY 155), with the right-of-way continuing in a business park as Madison Avenue Extension.
